Answer:
-27.5
Step-by-step explanation:
-100+60=-40, -40-25=-65, -65+37.5=-27.5
Bc and ef are congruent so that means
4x-7 =2x+3 subtract 2x from both sides
-2x -2x
_________
2x-7 = 3 add seven to both sides
+7 +7
________
2x = 10 divide both sides by 2
__ ___
2 2
x=5 replace x with 5
4(5) -7= 13
2(5) +3=13
both bc and ef equal 13
Standard form is Ax + By = C
y = (-3/4)x - 2
Multiply both sides by 4.
4y = -3x - 8
Add 3x on both sides
3x + 4y = -8
Your final answer is 3x + 4y = -8.
